Sunday: The ridge of high pressure that has dominated the recent weather pattern rebuilds, while lingering moisture from a weak disturbance will bring mid-level cloud. Winds will be very light and little to no significant precipitation is expected.Sunday:Alpine Temps: -3Freezing Level: 800mPrecip: TraceOutlook: Another weak shortwave will bring light precipitation Monday into Monday night. Mainly dry conditions are forecast on Tuesday & Wednesday. Freezing levels look to remain near 1200 m early next week. The models currently show a change in pattern way out in the future, on Day 8, which is Friday Feb. 17th. As many of you know, forecasting anything that far out can only be done with very little confidence.

Deep persistent slab avalanches remain possible with heavy triggers in shallow rocky snowpack areas on unsupported slopes. Check out the Avalanche Image Gallery under the Library tab for some photos of recent deep persistent slab avalanches in the region.

A thin eggshell/zipper crust formed on the eve of the 9th capping 4 cm of moist snow that rests on top of robust surface hoar created during the recent dry spell. This surface hoar is approx. 30 mm at ridge top and as large as 50mm in valley bottoms. 30cm of near-surface facets can be found on shady slopes while a suncrust has formed on sun exposed slopes. You may still find the odd pocket of wind slab at treeline and above. Concerns remain for the mid-December persistent weakness down around 80-100cm.
